Apple’s new Mac Professional accommodates loads of area so as to add as much as six PCIe playing cards. However in a little bit of irony, the desktop PC doesn’t assist third-party video playing cards—which frequently sit in a PCIe slot.
Apple executives addressed the lacking graphics card assist in a chat this previous weekend with blogger John Gruber, who runs Daring Fireball.
“Basically, we constructed our structure round this shared reminiscence mannequin, and that optimization,” John Ternus, Apple SVP for {hardware} engineering, mentioned… through the occasion. “And so, it’s not totally clear to me the way you usher in one other GPU, and achieve this in a means that’s optimized for our techniques.”

The identical chip can entry the Mac Professional’s shared RAM reminiscence, which may be configured at 64GB, 128GB, or 192GB. Consequently, Apple says the Mac Professional’s GPU can entry way more video reminiscence than different workstation graphics playing cards, which solely have 32GB or 48GB of reminiscence, for instance.
“With that 192GB, sure, it’s lower than 1.5TB [of RAM found in the 2019 Mac Pro]however it’s far more reminiscence for the GPU than any GPU has ever had earlier than,” Ternus mentioned.
Nonetheless, Apple’s resolution to nix the third-party video card assist could damage the product’s attraction, particularly since graphics playing cards from Nvidia have develop into very important to coaching AI algorithms for applications akin to ChatGPT.
In response, Apple’s SVP for advertising and marketing Greg Joswiak mentioned, “Look, Nvidia is doing job with that. There’s little question about it. We needed to deal with crucial issues to our prospects and we do these issues effectively.”

“The issues that we will do with our unified structure and with our M2 Extremely are issues that no person else can do,” he added.
Though the Mac Professional doesn’t assist exterior video playing cards, the PCIe Gen 4 slots can be utilized to connect networking or storage playing cards. This may make the Mac Professional higher for high-volume audio and video-editing duties over the smaller and extra inexpensive Mac Studio mini PC, Ternus mentioned.
The brand new Mac Professional goes on sale June 13, beginning at $6,999. However at maxed out specs, it may attain over $12,000.
